The following textbook is required.
I am aware that there are courses for which the textbooks are often optional - this is NOT one of those courses.
Software Engineering: A Practitioner's Approach,
7th Ed. Roger S. Pressman
ISBN:0-07-337597-7
Warning!
The International Edition (paperback) is much less expensive than the hardback.
However, the contents are NOT identical.
Chapter layout is slightly different, and the chapter questions are either different or in a different order.
If you opt for the International Edition it is your responsibility to resolve the differences!
